Putting Dates to the Past
Description
How do we put dates to the past? Learn about how we estimated the Earth’s age and the scientists who played a role, including Archbishop Ussher, Lord Kelvin, Arthur Holmes, and Willard Libby. This program will cover relative dating methods, absolute dating techniques, dendrochronology, radioactive absolute dating, carbon-14, and the Laetoli site and its significance. We’ll also explore the four main eras of human history: Precambrian, Paleozoic, Mesozoic, and Cenozoic.
